IMPROVEMENT IN MACHINES FOR PRODUCING VENTILATION.

Specification forming part of Letters Patent No. 208,855, dated October 8, 1878, application Ilcd July 19, 1878.

To all 'whom t may concern.- l

Be it known that we, CONRAD SenLnicHnn JOHN MACKERT, and J osnrH MACKERT, all of the city of Springleld, in the county of Clarke and State of Ohio, have jointly invented certain Improvements in Machines for Producing a Circulation of Air or Ventilation7 of which the following is a specification:

The invention rela-tes to a convenient portable machine carrying a number of fans, operated by springpower through a-system of gearing and belts, whereby currents of air are generated and kept in circulation in one or more compartments of a buildin g, car, orother structure, including` vessels, refrigerator-houses, te.

The object of our invention is to set in motion currents of air in places where an imperfeet ventilation exists, and particularly where an entire want of ventilation causes moldiness and putrefaction of a-rticles of food from foul air and gases, as in the dead-air chambers of refrigerator-houses, in cellars, &c., as well as iu close compartments of any kind where it is inexpedient to introduce air of a higher temperature by means of pipes or other system of ventilation.

To effect this we have constructed a portable machine carrying a number of fans of any approved form of construction, supplying its own power, so as to make it eonvenient for any of the purposes designed.

Figure l is a top View of our machine, in which A is the base frame on which it stands. B is an upper frame, in which is mounted a large spring, C, which is attached to the rear bar of the frame, and its inner end coiled around a drum on its shaft.

A bevel-wheel, 2, is fastened to the outside (left) end ofthe drum, into which a pinion, 1., gears on a winding-shaft, c', by which the machine is wound up, the usual retaining ratchet and pawl o p (seen on the opposite end of the drum) holding the spring O when wound.

The power is transmitted through the train of gears 3 4L 5 6 7 S 9 10 l1 12 13 14 to the fans a and a. The latter pair of fans are mounted on the tops of the two perpendicular shafts c e. (See also Fig. 2, which shows the machine in elevation.) These shafts are driven from the beveled gears 10 11. Their upper ends compartment, if necessary.

are supported by brackets f on either side of the machine, bent outward from the frame B, while their lower ends rest in an upright box, g, on Vthe base-rail A. These shafts may be extended to any desired height, so as to carry a Afan at their extreme upper ends in another They can at the same time carry one below on the same shaft, if required. "Hsa horizontal shaft at the front end of the machine, which carries the fans a, one ou each end. This shaft can also be extended to any length into a separate compartment, the whole being driven by the same power and gearing. A

The compact form of our machine makes it useful, especially for refrigerator-houses, where, as is well known, the ei'ects of foul air existing in the dead-air parts are injurious to the food placed therein, which can be kept sweet and wholesome by the circulation produced by it, and of uniform temperature-a desideratum entirely unprovided for in refri gerator-houses of the present construction.

It can also-be used in the steerage of a ves- 4sel, where the confined and uuagitated air breeds disease, and in hospitals, for the purpose of keeping a constant circulation throughout.

The machine may have its frame and gearing inclosed in a case, which can be made tight, so as to prevent the admission of moisture.

In positions where it is not easily accessible its winding-staff can be made to project through the wall or side of the compartment in which it is placed.

When used in hospitals, refectories, or other places where ilies are troublesome, brushes or other mountings can be attached to it in addition to the fans, tov aid in keeping away these insects, as well as for the purposes mentioned.

A sectional machine mounted upon a separate stand can be set ina separate apartment, either on the same floor or above the machine shown in Figs. l and 2, and driven from it by a belt from pulley b. (See Fig. l.) Fig. 3 shows one of these sectional machines with a single fan mounted thereon. Additional fans can be placed on it, if necessary.

XVe are aware that fans have been used for the purpose of driving currents of air through tubes 5' but we do not claim these.

We are also aware that trains of gearing driven by a volute spring for various purposes are old and well-known, and We disclaim them 5 but Ve claim as our improvement in machines for producing` a circulation of air for the purpose specified- 1. rlhe frame A B, with the series of horizontal and perpendicular shafts l c c, havin g fans a, and a', in combination with the train of gears 3 45 6 7 8 9 10 11 l2 13 14, the spring` C, and its windinggear 1 and 2, as and for the purpose hereinbefore set forth.
